Positive pressure respirator means a respirator in which the pressure inside the respiratory inlet covering exceeds the ambient air pressure outside the respirator. Powered air purifying respirator means an air-purifying respirator that uses a blower to force the ambient air through air-purifying elements to the inlet covering.
